Point to Point Communication: 5.8 GHz Circular Polarized Proximity-Coupled Feeding Antenna

Abstract

In this paper, point to point circular polarized 5.8 GHz patch antenna has successfully designed and simulated. This paper presented a design where both of the opposite edges of the rectangular patch of the antenna are truncated using proximity-coupled feeding technique. Both simulations of the proposed antennas had been analyzed. The objectives of this paper has been achieved which is to design and simulate the circular polarized antenna with operating frequency of 5.8 GHz. From the results, the proposed antennas with different feeding technique that radiate at a constant frequency showed some distinct value towards the size of the antenna and the characteristic of its radiation. The results indicate that the antenna that uses proximity-coupled feeding technique yields 3.551 dB directive gain, return loss and axial ratio at -10.015 and 2.225 dB respectively. Meanwhile, the directivity values for the antennas is 5.97 dBi. It can be conclude that by using proximity coupled fed technique, the gain of an antenna can be enhance thus increasing the antenna performance.
